Abstract
The effect of distance from neighboring Zelkova serrata canopy trees on the abundance of juvenile Z. serrata established in a conifer plantation was investigated in a heavily thinned plantation of Norway spruce (Picea abies L. Karst.) in Iwate Prefecture, northern Japan. The abundance of juvenile Z. serrata in the heavily thinned plantation was significantly higher than in an unthinned hardwood natural forest adjacent to Z. serrata canopy trees. Thinning and logging effectively promoted colonization of juvenile Z. serrata in the heavily thinned plantation. The mean abundance of Z. serrata juveniles decreased with distance from neighboring Z. serrata canopy trees. However, the local abundance of Z. serrata juveniles varied greatly, from 2,220 to 16,250 trees ha-1, even when the distance from neighboring Z. serrata canopy trees was equal to less than 1.0 times the canopy height of neighboring Z. serrata trees.
